After Effect Content Fill error

Hi, I'm getting a "Library Call fail" error when using content fill. I've noticed that it quickly takes up space on my C drive onto my desktop, and tends to crash for every test around with my drive space around only 200MB left. I have very little storage space here, but my HDD is almost all free. Is there a way to change it to a different drive? I've tried setting the media and disc cache there but it still outputs the fill files to my desktop.

Any ideas?

Thanks!
